This workshop aims to explore current and future biogeochemical budgets and dominant pathways as systems continue to go through degradation or recovery, using intensive modelling or field studies exploring hydro-biogeochemical process dynamics. A systematic approach is required for predicting water quality under conditions of climate change and land use change. Currently water quality assessment has been largely driven by catchment-specific case-studies and models, making comparison of approaches and outputs problematic. Contributions are invited to this workshop that compare water quality datasets and/or modelling approaches for assessing the response of water quality to a changing environment. Ideally, a model intercomparison using the same catchment datasets will be organised through the Panta Rhei Working Group “Changing Biogeochemistry of Aquatic Systems in the Anthropocene” and will build upon the WG’s workshop in China beforehand.
